Eeep! We're trying to figure out what's going on here. I do know that  
for this test it is *extremely* important to have optimization turned  
on (which it is by default). On my Powerbook, for instance (Apple GCC  
4.0.1), it runs in 12 seconds when compiled with -O2 vs. 16 minutes  
when compiled without optimization.

Are you perchance using the libstdc++ debug mode (_GLIBCXX_DEBUG)? We  
can tweak the test to make it faster if we need to.
